Parker Atchley is your typical four-year-old in many ways. He’s shy at first but usually opens up after he gets to know you, he loves anything with wheels, baseball and splashing in water, and he sticks pretty close to his mom, but a grandma will do if mom’s not available.

He’s an adorable, blonde boy with dark-rimmed glasses and a stare that makes you feel like he’s thoroughly assessing you but that also melts your heart.

He also is suffering from a rare disease—or at least a disease that only a few have been diagnosed with so far.
